Abstract:

Fluorine-containing hydrocarbons, which are commonly used as fluoroelastomer functional polymer monomers and fluororesin monomers, refrigerants, aerosol sprays, and foaming agents, were synthesized by the gas phase fluorination method. The method has the advantages of continuous production and avoi-ding serious corrosion to the reaction kettle, which simplifies the production process and becomes an important method for the production of fluorinated chemical products. This article summarizes catalytic reaction types and reaction mechanisms for the synthesis of HFOs are briefly introduced, and the catalysts used in gas?phase fluorination synthesis are summarized according to the main catalyst components. The traditional preparation methods(such as precipitation methods, etc.) and new preparation methods of various catalysts are introduced (Such as self?assembly method, solution combustion synthesis method, hard template method, electrospinning method, etc.), as well as catalytic performance, proposed the future development direction of the catalyst.

Key words: Gas-phase fluorination, Catalyst, Catalytic performance, Hydrofluoroolefins(HFOs)
